In our previous study [9], the core-shell SiO2/PAA/PS nanoparticles were synthesized through the combination of sol gel method and a dispersed polymerization approach, where the functional silica particles structured with vinyl groups on their surfaces were synthesized by the hydrolysis and polycondensation of tetraethoxysilane.
Since most researches are focused on emulsion polymerization, robust recipes for the particle synthesis are still necessary to prepare polymeric beads dispersed in organic solvent by proper synthesis method such as dispersion polymerization [16].
The polystyrene nanosphere suspension synthesized by dispersion polymerization was washed by centrifugation and redispersion in fresh ethanol to prepare dispersed phase.
Sol-densil, which is a nanosilica with mechano-chemically immobilized on its surface BAC [14, 16], was dispersed before polymerization in the initial mixture by the help of ultrasound.
Such organoboehmites are readily dispersed in the polymerization media such as toluene.
Both polynorbornene and polybutadiene-based particles were prepared by the respective ROMP of norbornene and cyclooctadiene initiated by (PCy3)2Cl2Rusing useveralveral methods of polymerization in dispersed media, such as dispersion, suspension and miniemulsion.

This paper presents a study on the stability of dispersions of multiwalled carbon nanotubes that are covered with α-pyrene functionalized polymers prepared via reversible addition fragmentation chain transfer (RAFT) polymerization and dispersed in different solvents.

It is observed that TiO2 has retained its structure even though it is dispersed in PAni after polymerization reaction [21].
